What does code P1758 mean?

Q: What does code P1758 mean?

Pressure Solenoid Control System Incorrect Current. P1758 on a Jaguar indicates that the transmission control module (TCM) has detected an incorrect current draw in the pressure solenoid control circuit, typically the line pressure solenoid. The TCM monitors the solenoid's electrical current and flags the code when the measured current falls outside the expected range for the commanded duty cycle, pointing to a fault in the solenoid, its wiring, or the TCM driver.
